We actually carry a broomstick designated as the "CAT scale stick". One end is wrapped with rubber repair tape so it gets traction on the button. (we do have another use for it: It's marked in inches and it helps us get centered in our back-in storage place).

Next time I will download the app.

Can you please elaborate? How do you employ the other use? marked in inches? Helps you get centered in your back-in storage place?? Must share more, please. Thanks! Rich

Pull on the scale. Make sure your front, rear, and trailer axle(s) are on separate pads.

Hit the button and hop back in your truck with the widow down.

Operator asks if it's a first weigh or a reweigh. Tell him first weigh.

Operator asks your truck number. Make up a two digit number. 00 works.

Unless the operator keeps talking, you're done. Pull off the scale and head inside to pick up your ticket at the register. They may ask if it's commercial or private. Tell them private.

Repeat as necessary, indicating "reweigh" when asked. I had to provide a code printed on the bottom left of my initial weigh ticket.
In addition to what's well described by The Greatleys, we found it useful to do a reweigh with both axles of tow vehicle on one scale, the unhitched trailer tongue on the second scale, and the trailer axles on the third scale. This gives you actual weight of TV without trailer, the tongue weight alone, and the weight on the axles with no tow vehicle involved.

And then a second reweigh with the original setup, but weight distribution bars disengaged. When compared to the first, this gives you the information about what weight is being distributed to the trailer axles and to the TV..

Your tongue weight should be 10-15% of yiur trailer weight. If not, you will want to shift trailer payload so that it dies fall within that range, keeping the heaviest items as close to the axles as possible for the best handling.

We walked inside between each measurement.

Please remember to be courteous to other users of the scales. When we used local CAT scales, there was no one behind us until the third weigh--then an 18 wheeler pulled in and we scooted of quickly, reattaching our WD bars while off the scales. Had he pulled in earlier, we would have pulled out and around and got in line behind him for our last measurement.

two and three scales used for a TV and AS22FB test

we used the cat scale in the Soo ( Sault St Marie)
the guy was very nice, he let us do two runs and asked us which one we like
this was our first CAT scale test

we did a two scale ( one for the TV and one for the AS22FB)
we did a three scale ( one for the front wheels and another for the rear wheels of the TV and one for the AS22FB)

this is how we parked for the two runs

we like the three scale test as it lets us know if the weight distribution bars and load in the TV and trailer are even around all three sets of wheels

Checked the CAT web site, and the video makes sense ... if you are an over-the-road driver behind an 18-wheeler.

What's the process for a humble driver and his Airstream?
This is what you will be experiencing:

When you pull on scales you will need to push the Call button for the attendant. They will ask for Company name just respond private. If that doesn't work just give your name as company name and say truck number 1 or whatever. You will also be asked if that is your first weigh. Say yes because when you go back around to reweigh it will be half the price.

1. When you pull on the scales you will see 3 different sections.
2. Drive forward to where your TV steer axle is on the first section and the
drive axle is on the second section.
3. Make sure that you don't drive too far forward because the Bambi axle
needs to be on the 3rd section.
I would weigh first round without WD engaged. Truck fueled, water tank full and all passengers and and cargo loaded. Then reweigh with the WD engaged.
I normally weigh the TV solo first fully loaded for trip and I step of the scale while its being weighed. This gives me a reference point.
I have also weigh the truck before loading it. Of course that is not possible if you hit the scales while on the road with your rig just do it the with and without WD engaged.

(I am fortunate to have a cat scale 15 minutes from my house so I can play around.)

At the storage site, we have poles on each side of our space. The polls are mounted on concrete pilings. If we go in perfectly we have 11" of clearance on each side. So we put the stick on the piling with 11" sticking out and aim to kiss it. Then we know we have good clearance both sides.

The stick is also threaded on one end so we can put our squeegee on it.

Was his security clearance adequate for that disclosure? Took years back in my day when tires were bias, we argued sedan versus wagon, and the AS keychain had a points file integrated.

Truck scales in Oregon are open all year long and many are low volume use and available to the public that aren't limited to commercial trucks. Sometime it can take a few hours to measure and weigh to get a very balanced set up. Once done properly, it can make a huge improvement in towing and handling.
Almost all RV dealers do not have scales and often I've helped members of our unit readjust their WD systems. I just helped a friend readjust her system set up by a major nationwide RV dealer. It was done so poorly it took 3 hours to completely reinstall and adjust the system. It was so bad, the torsion bars were screaming as she drove because the dealer had seriously over loaded the bars because the system was so far out of alignment.
The OP said he had a Bambi.

Single axle.

Over complicating things for them a tad me thinks.

Smart Weigh is THE BEST way to go. Escapees & RVSEF events usually have the service available for a modest fee. After you get PROPERLY weighed, a trained tech will go over your results and, will be able to tell you exactly what PSIs you should have in each tire. You'll also learn if you need to shift any major weight around (NO RV is perfectly balanced side~side. Sometimes an imbalance can be serious). Some of the events will also ACCURATELY measure your rig's height. Once you've been Smart Weighed, unless you make MAJOR changes to your set up, you'll never have to do it again.

SW has the single advantage of individual wheel weighing at one time. On a Cat Scale it takes a few more passes.

Plus changes need to be tested. And a yearly check against changes and unseen wear.

SW is a service I'd pay for. But there's not anything can't be done by the owner on his own. Just takes more time.
